Hi all, I'm trying to find out which, if any of the flathead 4x2 intakes had individual runners as opposed to a plenum. I did try posting on the HAMB, but little response. Thanks guys. Kev

Hi everyone. I have a model A roadster with a full hood, running a healthy 293” flathead underneath with 3 97’s on a straight linkage. The under hood temp can really get hot, surely sucking all this hot air into the engine can be no good for power?! However I’ve seen very few pics of lakes...

Hi. I’m in the process of grinding my valve seats to set the lash as I have non adjustable lifters. Due to the fact the valves aren’t at 90 degrees to the deck, my cutting tool is creating a larger valve seat contact area towards the piston as it is obviously contacting this area first. Could...

Hi all. The good folks over on the HAMB suggested I ask this on here. Does anyone know the max valve lift on an Edelbrock 1115 (flat)head. I've contacted Edelbrock but still awaiting a reply 4 days later. Also has anyone flycut these heads for extra valve clearance and know how much material...
